Title: Semiconductor device
Inventor: OYA MITSUNARI
IPC: H01L29/866
Filed: 1989-04-13
Abstract: PURPOSE:To prevent characteristics of a title device as a protective diode from being varied owing to variations in distance and withstand voltage from being varied by specifying a difference between the shortest distance between a short side of a high concentration N-type semiconductor region and the boundary of an N-type region and the shortest distance between a long side of said region and the boundary of the N type region. CONSTITUTION:A shortest distance L between a short side of a high concentration N type region 21 is defined and formed so as to be longer corresponding to the maximum of a positional displacement due to at least production variations compared with a shortest distance Ly between a long side of said region 22 and the boundary of the N-type region 21. With a title semiconductor device arranged as such, the shortest distance Ly between the long side of the high concentration N-type semiconductor region 22 and the boundary of the N-type region 21 is more shortened than the shortest distance Lx on the short side at all times even through there is produced variations of manufacture such as mask displacement and pattern shifting and the like. Accordingly, resistance on the long side is reduced to facilitate production of a surge current. Hereby, diode action and surge absorption are securely be achieved to prevent withstand voltage to static electricity and instability from being varied.

Title: Scanning exposure method, scanning aligner, and device manufacturing method using the method
Inventor: NISHI TAKECHIKA
IPC: G03F7/20
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To measure highly accurately at least one of the positions of a reticle and wafer in the directions of their synchronous movements with each other, by air-conditioning through air conditioning mechanisms the optical paths of the measurement beams of an interferometer system for measuring the positional information of the synchronous movement of the reticle with the wafer. SOLUTION: Since the optical paths of the beams of a laser interferometer 36A for an X-axis are long, independent air conditioning mechanisms of each other are mounted on the optical paths. Concretely, fixed covers (cylinders) for covering the optical paths of the beams are so provided that they cover the nearly whole region/partial regions of the optical paths including the one present between a beam splitter and a mobile mirror 34A and/or the one present between the beam splitter and a stationary mirror (it is fastened to the mirror cylinder portion of, e.g. a projective optical system), the beam splitter emitting both the beams which proceed respectively toward the mobile mirror 34A and the stationary mirror. By these air conditioning mechanisms, the optical paths of the measuring beams of the laser interferometer 36A for the X-axis are air-conditioned.  As a result, the variation of the measurement value of a scanning aligner caused by the fluctuations of its air conditionings, etc., is prevented from occurring in the course of its scanning exposure even when its optical paths becomes long.

Title: Cpu resetting circuit
Inventor: FUJITA NATSUO
IPC: H03K17/22
Filed: 1984-05-09
Abstract: PURPOSE:To discharge quickly the charge charged to a capacitor and to avoid the resetting failure by adding a discharging circuit of the capacitor in case a power supply is cut. CONSTITUTION:A discharging circuit passed through a diode 14 is added for a capacitor 61 in case a power supply is cut. The capacitor 61 is discharged in a short time since the resistance level of the discharging path is low. The electrostatic capacity of the capacitor 61 is set smaller than that of a capacitor 60. Therefore the greater part of the output voltage of an AVR2 is applied to the capacitor 61 when the power supply is kept on. Thus the voltage of a series circuit of capacitors 60 and 61 has a sudden drop when the capacitor 61 is quickly discharged. A sufficient current flows to a resistance 7 when the voltage of a terminal 3 has a rise after the power supply is recovered. Then a pulse having the large peak voltage is produced at a terminal 4. This prevents the resetting failure.

Title: Torque detecting device
Inventor: SEKINE YOSHIO
IPC: G01L3/10
Filed: 1984-05-09
Abstract: PURPOSE:To detect the size and direction of an applied torque without contacting by detecting the difference in the change of the permeability of two magnetic layers provided on the outer periphery of a receiving shaft. CONSTITUTION:The inductance of detecting coils 8, 9 is equal as well due to the permeability of the 1st and 2nd magnetic layers 5, 6 being equal under the condition of a torque being not applied on a shaft 1. When a torque T is applied, the 1st magnetic layer 5 receives a tensile stress almost and the permeability becomes bigger and the 2nd magnetic layer 6 receives a compression stress almost and the permeability becomes smaller due to each magnetic layer 5, 6 having sufficiently long and slender shape. Therefore the inductance of the detecting coil 8 becomes bigger and the inductance of the detecting coil 9 becomes smaller and so by taking the difference a positive signal proportionate to the size of the applied torque is obtainable.
